ITEM-INDICATOR.

Application filed November 11, 1912.

To all whom it may concern Be it known that I, HENRY KfiN'rzLER, a citizen of the United States, residing at 407 Main street, Luzerne, Luzerne county, Pennsylvania, have invented new and useful Improvements in Item-Indicators, of which the following is a specification.

This invention relates to item-indicators and is more particularly designed for use on calculating machines. It may readily be applied to other machines, however, to count operations, articles or what not.

One object is to provide an improved and simplified item indicator which. is readily attachable to a variety of calculating machines now on the market without material change, instead of being confined to a special type.

The invention comprises an indicator driven from the main driveshaft, the connection between the main drive shaft and the indicator being normally disabled, so that the indicator will not register on an idle stroke of the machine, together withan adjusting means controlled by some part common to machines of various types, and shiftab-le only during an effective stroke, to render said connection operative. Furthermore, means controlled by mechanism operated when a total is to be taken whether the register is cleared or not, disables said connection during such totaling or clearing stroke, to prevent a registering operation of the item-indicator.

Other objects and advantages will be more fully set forth hereinafter, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan View of one embodiment of this invention applied to the well-known Wales adding and listing machine. Fig. 2 is a view of the left side of the machine at rest, to illustrate the connection between the indicator proper and the usual mechanism employed in a Wales machine. Fig. 3 is a detail perspective of the indicator-operating mechanism. Fig. 4 is a side view, showing the position assumed by the indicator-operating mechanism during the forward stroke of the main drive shaft, but prior to the engagement of the counters with their drive members. Fig. 5 is a similar View, showing the positions of the parts at the end of said forward stroke, the indicator having been operated. Fig. 6 is a longitudinal sectional Specification of Letters Patent.

view, showing one means to operate the adusting mechanism. Fig. 7 is a detail perspectlve of a part of the gang of drive members, and the adjusting mechanism. Fig. 8 1s a side view, showing the draft mechanism and lndicator disengaged by depression of the total key. Fig. 9 is a similar view,

taken when the main drive shaft is at the end of its forward stroke.

Reference is made to patents to McFarland, 842,232, Jan. 29, 1907; and to Wales 797,032, August 15, 1905, to illustrate and explain such parts of the Wales machines as are not herein fully disclosed.

The side frames 1, 1 (Fig. 2) support a keyboard mechanism, a registering mechanism, and a printing mechanism including type carriers 2, (Fig. 6). This mechanism is inclosed within a casing 3 (Fig. 1) cut away to afford access to the keys 4, and having a transparent plate 5 through which the counters 8 of the registering mechanism are visible.

The keys 4 are preferably arranged in banks, as shown in Figs. 1, 2 and 6. Depression of the keys rocks levers 5 to project stops 6 above a housing 7, said stops being arranged in rows to correspond with the banks of keys controlling them.

Counters 8 are individually rotatable upon an axle 9 mounted at its opposite ends in arms 10 pivoted at 11 to the side frames. Props 12 (Fig. 4) pivoted at 13 to the arms 10 are slotted at their lower ends to rest on a trip rod 14 supported by links 15 (Fig. 2) from shaft 16 and connected by links 17 and cranks 18 with the main drive shaft 19. A handle 20 (Fig. 1) may be used to turn said drive shaft.

The main drive shaft 19 when turned on its forward stroke, operates the connecting links 17 to swing the trip rod 14 in a descending arc to lower the props 12 and with them the axle 9 and counters 10. Legs or supports 21 connected to the opposite ends of the axle 9. normally lie in line with seats 22 on the side frames 1, so that as the axle starts to descend, the legs rest on the seats (Fig. 4) to hold the counters idle until the main shaft has nearly reached the end of its forward stroke. Meanwhile the ends of the trip'rod 14 travel idly, relatively to bridle links 23 connected at 24 to the legs 21, until toward the end of the forward stroke of the main drive shaft, the trip rod 14 strikes the 110 ends of the links 23v (Fig. to dislodge the legs from their seats, whereupon the counters descend to engage pinions 31 (fast with each counter) with drive members 25 (Fig. 6). These drive members 25 are preferably rack-bars, pivotally mounted on front and rear arms 27 and 28 journaled on shaft 16 and cross rod 29, respectively. Springs 30, preferably connected to the rear arms 28, drive the rack bars forwardly. A bail 32. carried by arms 33 fast on a rock shaft 34, normally, contacts the forward rack-supporting arms 27 to restrain the rack members 25 against operation. On the forward forces the bail 32 against the forward arms 27 which have rocked forwardly, to return the arms and restore the drivemembers 25 to normal position. The drive members, as they are retired, turn the counters 8 to register or accumulate amounts corresponding to the values of the keys depressed. The main shaft, on its return, also restores the trip rod 14, the preliminary throw of which rod is idle, to enable the drive members to turn the counters, after which the trip rod swings upwardly to disengage the counters from the drive members and enable springs 36 to return the legs 21 into line with their seats 22.

The rear arms 28 may each have rearward extensions 37 (Fig. 6) to position the types of type carriers 2 relatively to the printing line on a platen 38 (Fig. 1). When the drive springs 30 advance the drive members 25, the latter rock the arms 37 to bring the proper type to the printing line, said type carriers being retired by the return of the drive members,

Depressing the total key 39 (Figs. 1, 2, 8

- and 9) rocks levers 40 on opposite sides of the machine, connected by the cross shaft 16. Links 41 connect. arms 40 of said levers with the supports or legs 21' to swing the latter out of line with the seats 22, when the levers 40 are rocked by depressing the total key. A loose connection 42 (Fig. 8) between one of the arms 40 and a connecting bar 43 guided on pins 44, enables the key 39, when epressed, to thrust said bar forwardly. A

cam 45 on said bar wipes a crank 46 on a shaft 47 to rock the latter and with it a displacing bail 48 (Fig. 6) connected thereto mes es 32 frees the drive members to the action of their drive springs 30, which springs advance the drive members until the latter are arrested by abutments (not shown) on the counters 8, said checks forming part of the zero-resetting mechanism V disclosed in patent to McFarland, 842,232, January 29, 1907. The drive members on their advance, reverse the direction of rotation of the counters from that in which they are turned in registerin andat the arrestof the drive members l oy said checks, the counters have been restored to zero position, and the types in the type carriers 2 positioned to print the total registered by the'counters at the depression of the total key. The printing operation occurs, and, providing the total key is released at the end of the forward stroke, the counters are disengaged from the drive members which then retire idly, leaving the counters at zero. In taking a sub-total, the total key is held down throughout nearly the entire operation, to prevent the disengagement of the counters and drive members on the return stroke. As a result, the drive members when being retired, turn the counters, as in the adding operation, to again register the total amount disclosed total key. i

The foregoing construction is old and only constitutes part of the present invention, in so far as it is combined with the new devices now to be set forth.

To indicate the number of items registered prior to depression of the on the machine, an item indicator 50, of any suitable construction is preferably removably secured to the machine, Said indicator includes a gang. of numeral wheels 51 mounted on a shaft 52, and driven in any convenient manner, as by an operating lever 53. The indicator mechanism per 86 is immaterial to the present invention, and any suitableform now on the market may be assumed to be employed, for present purposes.

The inner end of lever 53 (Fig. 3) is con- .nected to the operating mechanism of the .indicator, said lever projecting through a slot 54 in the casing of the indicator. It is highly advisable that the indicator be operated only when an item is registered or printed or both; that the indicator remain idle during the operation of taking a total and clearing the machine, or'of taking a sub-total; and that the indicator remain at rest during any "idle stroke of the machine, that is, one in which no item is set up on the keyboard, to be registered or printed. Therefore, I contrive by the employment of simplified and improved mechanism, to rock the lever 53 by draft mechanism operated from the drive shaft 19, but normally ineffective, and to automatically effect the adjustment of said draft mechanism, to effective position, by means which operates only when an item is to be registered or printed or both. Furthermore, I contrive to disable the draft mechanism when a total or sub-total is to be taken or the machine cleared, by the operation of the usual mechanism for eflecting these operations, so that though the adjusting mechanism and the draft mechanism operate, the latter will not efl'eta registration on'the indicator.

A draft bar 55 (Figs. 4 and 5) is con nected at 55 to the prop 12 which, as before explained, is rocked back and forth by the trip rod 14 connected by links 17 and cranks 18 to the main shaft 19 to be operated thereby at each stroke. Said draft bar is preferably supported for reciprocatory movement and carries a hook or coupling member .56 (shown best in Fig. 3). A transmission lever .57pivoted at 58, carries a coa direction transversely to the path of the operating hook or coupling member 59 loosely mounted :thereon to shift thereon in hook 56. Said hook 59 normally lies out of the path of the hook 56 so that upon an idle stroke of the main drive shaft, no coupling is effected and the indicator-remains at rest. Such loose connection may be effected by pins 60 (Figs. 4 and 5) on the lever 57, assing through a slot 61 in a plate 62 rom which projects the shiftable coupling member 59. Preferably, a link'63 pivoted at 64, to an extension of the lever 57, connects the latter with the operating lever 53 by means of a wrist 65 entered in and normally occu pying one arm 66 of an angular slot formed in the operating lever.

To render the draft mechanism effective, I contrive an adjusting mechanism (Figs. 3 and 7) comprising a universal bar 67 overlying the arms 37 of the drive mechanism and carried in arms 68 swung from the rod 29; and an adjuster or tappet69.

In a calculator of the general type to which the Wales machine belongs, whether it registers only and includes no printing mechanismor, vice versa, prints but has no registering mechanism, means must be provided either to drive the counters of the register, or to position the type carriers of the printing mechanism, or both. In the present instance, the arms 37 constitute such means and will be operated whether the machine is arranged to add only, to print only, or to both add and print. Hence the invention is applicable to different styles of machines of the same general type and is not confined to a single style, as a machine having a locking keyboard, for example.

At every efi'ective stroke of the main drive shaft, one or more of the arms 37 rock, upwardly, and they in turn rock the universal bar 67, one of the arms 68 of which carries the adjuster or tappet 69. The tappet carried upwardly by the arm 68 strikes the edge 70 of plate 62, lying beyond the transmission lever 57, to shift the hook 59 into the path of the coacting hook 56, which latter as it advances picks up the hook 59 and draws it forwardly to rock the transmission lever lies in advance thereof, to afiord the adjusting mechanism time in which to shift the coupling 59 into its ath.

On the return stro e of the main shaft 19, the drive members 25 are retired, and with them, the arms 37, which permits the adjusting mechanism to return to idle position.

During the return ofithe draft bars 55, the coupling 56 wipes over an incline 73 (Fig. 3) on the coupling 59, 62, to restore the latter to normal position, and also strikes the transmission lever 57 to restore the latter and, through the connecting link 63, return the operating lever 53.- A spring74 may assist the return of the operating lever.

In taking a sub-total, or in taking a total and clearing the machine, it is desirable that the indicator remain idle. Depression of the total key 39 advances the connecting bar 43 (Fi s. 8 and 9) through lever 40, arm 40 thereo and connection 42. A \catch or shifter 75 on the connecting bar lies behind the link 63 and when the connecting bar advances, the catch shifts the link so that its wrist 65 lies in line with the open end 76 of the angular slot 66 in the operating 1ever 53. Upon turning the main drive shaft, the coupling 56, 59 is rendered effective and the transmission lever 57 is rocked to operate the link 63, the wrist 65 of which works idly in the open end 76 of the angular slot without rocking the operating lever. Upon the retirement of the connecting bar 43 to normal position, which occurs when the total key 39 is restored, either at the endof the forward stroke and the commencement of the return stroke, (as when taking a total and link and with it the wrist 65 back to efiective connection with the operating lever 53. Turning a knob 78 on shaft 52 resets the numeral wheels 51 of the indicator to zero.

From the foregoing it will be seen that I have provided a mechanically or automatically operated adjusting-mechanism driven.
